Trying to change the IP address of a remote Ubiquiti device in this case a Nanobeam - but usually works for any Ubiquiti radio I've tried before.

Note process I used was add 192.168.1.10 on interface of Mikrotik that Nanobeam is plugged into.

Then SSH from Mikrotik terminal into ubnt linux CLI.


Note I'm not experienced in Linux command line - so am just following what I've learnt from a friend and copy and pasting what usually works.

In this case, once into the CLI of the UBNT I copy and paste:

ip a a 172.16.1.46/30 dev br0

ip r del default

ip r a default via 172.16.1.45

Which usually works, then I can login to 172.16.1.46 on my browser and update the device to the settings I want.


But now for some reason, it returns the No such process error after line 2 & line 3:

XW.v6.3.2# ip a a 172.16.1.46/30 dev br0
XW.v6.3.2#
XW.v6.3.2# ip r del default
RTNETLINK answers: No such process
XW.v6.3.2#
XW.v6.3.2# ip r a default via 172.16.1.45
RTNETLINK answers: No such process


HELP!!

If you googled the second error, you would find that it normally means that the device can't reach the router, in your case 172.16.1.45. This is strange, since you added an address in the 172.16.1.44/30 subnet to br0. But are you sure this addition was successful?

The first time you get the error, perhaps you do not have a default route.
